LOW DISTORTION LINE DRIVER
The AD828 can quickly be turned into a powerful, low distor-
tion line driver (see Figure 10). In this arrangement, the AD828
can comfortably drive a 75 Ω back-terminated cable with a
5 MHz, 2 V p-p input, while achieving the harmonic distortion
performance outlined in the following table.
Configuration
1. No Load
2. 150 Ω R
3. 150 Ω R
In this application, one half of the AD828 operates at a gain of +2.1
and supplies the current to the load, while the other provides the
overall system gain of +2. This is important for two reasons: the
first is to keep the bandwidth of both amplifiers the same, and
the second is to preserve the AD828’s ability to operate from low
supply voltage. R
satisfy the following equation:
